When connecting inverters to a third-party management system, you need to ensure that the
third-party management system supports the standard Modbus TCP protocol and configure the
access point table based on the definitions of Huawei inverter interfaces. You need to set NMS
server and NMS server port for inverters as required by a third-party management system and
replace the client certificate. A third-party management system must comply with the definitions
of Huawei inverter interfaces. You need to obtain inverter interface definitions from Huawei
technical support. This document describes how to connect inverters to a Huawei management
system.
Installing the Dongle
2.3
• Before installing the Dongle, you need to remove the Bluetooth module or USB data cable.
• Each inverter has only one USB port. When maintaining an inverter locally, you need to
remove the Dongle. In this case, the communication between the inverter and the network
management system is interrupted. After the local maintenance is complete and the Dongle is
installed, the communication is automatically restored.
1. Install a SIM card.
NOTE
• You need to prepare a standard SIM card (size: 25 mm x 15 mm; capacity: ≥ 64 KB). When
connecting to Huawei Hosting Cloud, prepare a SIM card based on the traffic requirements in
the following table.
• Before installing a SIM card, you need to remove the Dongle from an inverter.

FAQ
How Do I Set Export Limitation Parameters?
Set export limitation parameters for the master inverter.
•
SUN2000-(3KTL–20KTL) as the master inverter: Log in to the FusionSolar app as installer, and
choose Device maintenance > Energy control > Grid-tied point control > Active power to
set related parameters.
•
A commercial smart inverter as the master inverter: Log in to the SUN2000 app as Advanced
User, and choose Settings > Grid-tied Point Control > Active power control mode to set
related parameters.
What Should I Do If Slave Inverters Cannot Be
Connected In the Cascading Scenario Where a
Commercial Smart Inverter Functions as the Master
Inverter?
•
Ensure that the RS485 communications cable is securely connected to the slave inverters.
•
Log in to the SUN2000 app as Advanced User, choose Settings > Comm. Parameters >
RS485, and ensure that the RS485 parameter of the slave inverters is set correctly.
•
Log in to the SUN2000 app as Advanced User, choose Settings > Comm. Parameters >

The Dongle has no SIM card or the SIM card is
in poor contact. Check whether the SIM card
has been installed or is in good contact. If not,
install the SIM card or remove and insert the
SIM card.
The Dongle fails to connect to the management
system because it has no signals, weak signal,
or no traffic. If the Dongle is reliably connected,
check the SIM card signal through the APP. If
no signal is received or the signal strength is
weak, contact the carrier. Check whether the
tariff and traffic of the SIM card are normal. If
not, recharge the SIM card or buy traffic.
No communication with the inverter
•
Remove and insert the Dongle.
•
Check whether inverters match the Dongle.
•
Connect the Dongle to other inverters.
Check whether the Dongle or the USB port
of the inverter is faulty.
